-g(-2) is 10
<u>Step-by-step explanation:</u>
Step 1:
Given g(x) = 3x - 4. Find g(-2).
⇒ g(-2) = 3 × -2 - 4 = -6 - 4 = -10
Step 2:
Find -g(-2)
⇒ -g(-2) = -(-10) = 10
Well.
The relation between the circumference of a circle and its diameter is described by the following equation:

where d is the diameter of the circle.
For a giving diameter (d=3ft), we can substitute in the previous equation
The circumference of a circule= 3.14*3 (you can use ur calculator to find the exact number i guess it will be about 9.42 ft)
